Problem:
I was working on a 2019 Ford Mustang with all keys lost. It’s a push-start model with the alarm active. Using the Xhorse VVDI Key Tool Plus, I was able to generate an emergency key, but the vehicle was completely unresponsive to it. Why this might happen or what I could be missing?
Solution:
Ford all smart keys lost programming requires at least 2 keys.
Two keys required.
